This invention relates to spraying devices which may be used as a hre extinguisher or a sprayer for insecticides in which a stream of iuid is ejected from a container orreservoir by pressure, such as liquid pressure applied to tA e liquid in the container or by a reduction ot pressure in the container by withdrawing and discharging the liquid Jfrom the container by a pumping mechanism.

L is a primar y object of the invention to provide a device of this character wherein the pumping mechanism is adjustahly mounted upon the exterior of and in communication with the interior of, the' container, which pumping mechanism in the operative position thereof is adapted to extend laterally oi' the container, and in the inoperative position thereoil to be folded to lie in contiouous relation to the container forming a compact structure readily stored and transported.

it is a further object of the invention to provide a spraying device orp this character wherein the connection ot the pumping mecha ism with the container is through the The connection i'urther permits the pump mechanism to be opened to the container in the operative position thereof, and to be shut cti therefrom in the inoperative position of the pumping mechamsm.

it is another obj'ect of the invention to provide a spraying device of this character wherein the pumping mechanism is arranged to inject and create an air'pressure within the container to ziert an expelling force upon the liquid therein. rihe container is arranged with outlet means adapted to be placed in communication with the atmosphere when vthe pumpino` mechanism is in the operative positionwhile at the same time the pumping mechanism is also placed in communication with the container. ln theinoperative position of the pumping mechanism, the outlet means is adapted to be closed and the pumping mechanism shut ott7 from the interior of the container. n

Other objects and advantages will hereinafter appear.

ln the embodimentoi the invention illustrated in the drawings there is provided a pumping mechanism of the reciprocatory piston typeto create an air pressure in the container or reservoir as the expelling torce :for the liquid, the container having a check valve controlled air inlet passage into and aliquid outlet passage from the container through a pump supporting and mounting member or bracket fixed upon the container, the pumping mechanism being fixed `to a supporting member having a passage therethrough in communication with an Aair outlet port or ports from the pump cylinder, and the pump carrying discharge means in communication with the passage through the pump supporting member and by means of which supporting member the pump mechanism is pivotally mounted upon the pump supporting bracket upon the container. The passages in the pump supporting member as the pumping mechanism is moved to operative positon are automatically placed in communication with the air inlet passage and liquid outlet passage in the supporting bracket, and as the pumping mechanism is adjusted or moved to inoperative position the air inlet and liquid outlet passages through the supporting bracket are automatically closed, means being provided to yieldingly and releasably retain the pumping mechanism in either its operative or inoperative position. i

rl`he embodiment ot the invention shown in the drawings comprises a reservoir or container 13 to contain the liquid to be discharged and in the use ot the device as a fire extinguisher preferably consisting of carbon tetrachloride, said container being substantially ot semi-circular form in cross 'section with the wall opposite the curved wall of the container bulged inwardly, as shown at 14 in Figure 2, to form a recess in the wall extending longitudinally7 thereof. The container is arranged with a filler opening in one ond or the tcp having a removable closure cap, as at 15, and also has tiXed at said end a member 1G for the connection of a. looped strap for engagement over the shoulder ot a person using the device to readily7 transport the same and permit ot' the use of both hands in manipulating the pump and directing the discharged stream.

A bracket 18 is tired te one end of the container in interposed relation to the inwardly bulged portion 14: and the opposite wall of the container whereby to support and adjustably mount a pumping mecha.- nism, in the present instance of the air pressure type. This bracket has a base portion whereby it is suitably mounted upon the container.

In the embodiment illustrated the pumpingk mechanism may embody either a single or double acting pump7 a pump ot the single acting type being shown, air being discharged from the pump only during the torward stroke of the pump piston. The pump comprises a cylinder 35 having heads 36, 37 at opposite ends. The pump piston is in the form of a disk of tiexiblo material ot' greater diameter than the pump cylinder (Fig. 111), said disk being secured on a piston rod t8 between a pair of washers 8G, 8? having threaded connection with the reduced end of the piston rod, the washer S6 being of substantially the same diameter as the pump cylinder and the washer 87 ot slightly less diameter. The piston rod e7:- tends through the head 36 and has an operating handle 50 tif-led thereto, the rod haring a loose lit in the cylinder head thus permitting the entrance of air into the pump cylinder in back of the piston which passes tothe front of the piston between the piston disk 85 and cylinder, due to the iiexibility of said disk, during the outward nio-'vement of the piston, and as the piston is movedr into the cylinder the disk will spread making a. substantially tight seal between the piston and cylinder forcing the air in Jfront ot' the piston out through a port 88 (see Fig. 8) in the cylinder head 37. The port extends laterally and is Aconnected by a pipe 89 with a` passage 90 (see Fig. G) in a pump support 5&1', the passage having an outlet port 91 with the outer end thereof ot increased diameter and arranged in a boss 91 extending from the pump support as shown in said Figure G for a purpose to be hereirafter described. This support has a recess 59 of circular shape in cross section wherein the pump is secured, and al bifurcated portion with pertorations therein as shown at 92 in Figure 5 whereby it is pivotally mounted with the pump upon the mounting bracket 18 by engaging the biturcated at the outer sides of a pair ot ears or lugs 93, the ears having pertorations to reg ster with perforations in the bifurcated member Pertorations are also provided in the plates 94 at the sides of the supporting brackets registering with ,the pertorations in the lugs 93 and the bifurcated extensions 92. Si headed stud 95 extends through the hole.' in the plates 911 and also through the previously mentioned registering per'iorations and secured by a nut 96; thus providing a hinged joint whereby the pump may be swung relatively to the container.

The pump also carries a discharge nozzle 64: in an opening in the lateral extension of the cylinder head 37 which communicates with a pipe 63 connected to a passage 9G in the pump support 5i (Figures 5 and l) having an outlet 97 with the outer end et the port of increased diameter and arranged in a boss 97 extending from 'the pump support. The wall of the passage has an lltl lle',

opening therein inline with the port 97. A plug is iXed in the port 97 having a. portion of reduced diameter or a pin extending axially through the port 97 to substantially the end of the boss, as at 98, for a purpose to be hereinafter'I described. and 9T when the pump is adjusted to operative posit-ion to extend laterally of the container are engaged in correspondingly formed recesses 99, 99 in the e mounting bracket 18 and sealed by engaging washers 102 of sealing material seated in said recesses, as clearly shown in Figures 8 and 9, placing the port 91 connected with the air outlet oithe pump in communication with an inlet port to a passage 100 extending through the mounting bracket having an outlet in communication with a port in the container, as at 101. (Figure rlhe passage Y 100 is normally closed through the port 100 by a spring influenced valve comprising a circular head 103 engaging in a. similarly formed enlargement at the inner end of the port 100 and having a suitable material recessed in the end thereof to; seat against the shoulder formed by Vthe inner enlargement to seal the port, as clearly shown in Figure 8. The head is carried by or is integral with a stem 10a whereby the valve is slid-.ably mounted in a shouldered plug 105 threader in opening in the mounting bracket arranged coaf-ially of the port 100 and serving to connect said port with the passage 100", the valve being normally urged to its seat by a. spring 106 coiled about the valve stem and confined between the valve head and the plug. rlhis valve is unseated when the pump piston is moved into the pump cylinder by the air discharged from the pump cylinder through its connection with the port 100, the air thus being delivered from the pump into the. container to create and store an expelling air pressure for the liquid therein. n Y Simultaneously with placing the pump in air communication with the container as above described, the nozzle 64 is likewise placed in communication with the container. This is effected when the boss 9T on the pump support seats in the recess 99 in the mounting bracket. This places the port 9T in communication with a port 107 positioned axially wlth respect to the recess 99', and which in turn communicates with the passage 108 eX- tending through the mounting bracket 18. A tube 84; opened at its lower end is connected to this passage, thus providing a duct through which liquid'from ythe container ma.7 be expelled. lThe container is formed with a dish-'shaped bottom into which the ei;- peiling tube extends in order that practically all of the liquid in the container may be utilized. As the tube 34 is always immersed in the liquid a seal is provided which pre- The bosses 91 n vents the air from passing to the liquid outlet.

The interior of the container and thereby the liquid therein is shut off from the atmosphere through the port 107 by a spring influenced valve similar to the `shut oft valve for the air inlet 100. The valve comprises a head 103, of rect-angular shape as shown in Figure 10 instead of circular as the valve head 108. The port 107 has an enlargement or" circular shape at the inner end for seating the valve and is of greater diameter than the cross sectional area of the valve head. The corners of the head are rounded, as shown at 109 in Figure 10, providing surfaces engaging the wall of the port enlargement and leaving spaces between the sides of the valve head and port enlargement for the passage of the liquid to the port 107 whenthe valve is unseated. The valve also has a suitable material seated in the end thereoi` to seat against the shoulder formed by the enlargement of the portI 107 to yseal the port when the valve is seated, as shown in Figure 9. The

valve head is carried by a stem 104 slide' ably mounted in a shouldered plug 100 threaded into au opening inthe mounting bracket in co-aXial alinement with the port 107, which opening serves to connect the passage 108 and port 107. The valve is normally urged to its seat by a spring 106 coiled about the valve stem and conned between the plug and valve head. It will be obvious that any pressure of the liquidkin the container will exert al seating force upon the valve head 103, and to unseat the valve and open communication between the nozzle and the container through the port 107 the pin 98 extending through port 97 is adapted to engage with a stem 110 extended from the valve head opposite to its carrying stem and through the port 107 when the pump is moved to operative position. As soon as the pump is moved to its inoperative position the pin 98 is moved out of engagement with the valve pin and the valve is immediately seated by its spring.

To lockthe pump in its operative position or that extending laterally of the container spring iniiueuced detents 111 in the form of shouldered pins are carried in recesses in the opposite sides oi the pump support, (Figure 5) and are normally projected to a predetermined extent beyond the sides of said support, said detents being adapted to automatically engage in perforations 112 in the side plates 94 of the mounting bracket 18 when the pump is positioned substantially horizontally to the axis of the container. rhe pump is readily released from this position by exerting a sudden force on the pump in the direction of the container. Y

The ypump is releasably secured in its inoperative position in contiguous relation to and in the reduced portion 14 ,of the con` tainer by a U-shaped resilient retaining member 113 (Figure 13) secured in the reduced portion of the container and adapted to embrace the pump cylinder at opposite sides beyond its greatest diameter. To Yaclitate the release of the pump from said retaining member the outer end of the head 37 has a recess 37 therein 'for the engagement of a linger or fingers whereby to readily grip and exert an outward pull on the pump.

To prevent the accumulation of foreign substances at the mounting of the pump support 54e the one edge of the side plates 941 is made of arcuate form, as at 94K, having its center of curvature located at the center of the pump pivot support 95. A hood 114 is fixed to the pump support, said hood having a part to conform to the curvature of the plate edge 9i and its opposite ends arranged at slightly less than a right angle and bent to extend in parallel relation, as shovvn at 115, to embrace the outer surface of the end Walls 94 the plates being pivotally supported upon the pump pivot support 95, as clearly shown 1n Figures 1 and Q. To prevent denting of the air conducting and nozzle carrying ipes S9, 63, or otherwise injuring the same, a shield of sheet metal 1,1 is provided, this shield extending between the cylinder head 37 and the pump support 5l and embracing the pump cylinder at the opposite sides thereof of greatest diameter.

To releasably lock the piston in its innermost position in the pump cylinder the cylinder head 36 (Figures 11 and 12) is extended beyond the end of the cylinder and arranged with an annular recess, as at 117. The pump operating handle has a recess 116 in the end and said recess has an annular enlargement 118. A member of resilient material 119, formed substantially of U shape is engaged in the annular enlargement 118, said member having the connecting portion arranged in an arc substantially 'the same as the curvature of the recess enlargement 113, and the legs arranged in parallel relation and spaced apart a distance substantially the same as the diameter of the annular recess in the extended portion of the cylinder end, said legs having their ends curved inwardly to extend into the enlargement of the recess 113 opposite to the connecting portion of said member, as clearly shown in Figure 2i. By this arrangement as the pist-on is moved inward and the bottom of the recess in the end of the handle engages with the cylinder head 3G the legs of the resilient member will bel sprung laterally to engage behind the shoulder formed by the annular recess 117 in the cylinder head. The operating handle may be readily released for operating the piston by exerting an outward pull on the handle thereby unseating` the resilient retaining` member from in back of the shoulder formed by the head recess 117.

While the spraying device is out Aof use or in storage the pump is secured contiguous to the body of the container and the container is sealed from the atmosphere by the valves 103, 103 arranged in the pump carrier 13. To place the device in operation the pump is positioned to extend laterally from the top of the container positioning the ports 91 and 97 of the pump support in communication with the ports 100 and 107 of the pump carrier, respectively, the air being forced from the pump through the ports 91 and 100 opening the valve 103 and permitting the air to enter the container through the passage 100. The horizontal positioning` of the pump opens the valve 103 in the port 107 allowing the liquid to be propelled -from the container through the intake pipe .341, passage 108, ports 107 97, passage (53 and nozzle 64.

It will be obvious that various modifications may be made in construction and arrangement of parts Without departing from the scope of the invention.
